Surface dressing - Test methods - Part 2: Visual assessment of defects

This European Standard specifies methods of assessment of the defects which may occur with a surface dressing. The assessment of the defects evaluates the condition or performance of the surface dressing and, thus, gives an indication on the durability of the surface dressing. This standard is applicable to all surface dressings (roads, airfields and other trafficked areas). The checklist in Annex A (normative) is a preliminary to the test method.

Oberflächenbehandlung - Prüfverfahren - Teil 2: Visuelle Beurteilung von Inhomogenitäten

Diese Europäische Norm beschreibt Verfahren für die Beurteilung von Fehlern, die bei einer Oberflächenbehandlung auftreten können. Die Beurteilung der Fehler dient zur Bewertung des Zustandes oder der Wirksamkeit der Oberflächenbehandlung und folglich als Hinweis auf die Haltbarkeit der Oberflächenbehandlung. Diese Norm ist auf sämtliche Oberflächenbehandlungen anwendbar (Straßen, Flugplätze und andere Verkehrsflächen). Der im Anhang A (normativ) angegebene Aufnahmebogen ist eine Vorstufe des Prüfverfahrens.

Enduits superficiels d'usure - Méthodes d'essai - Partie 2: Evaluation visuelle des défauts

La présente norme européenne spécifie des méthodes d'évaluation des défauts que peuvent présenter un enduit superficiel d'usure. L'évaluation des défauts consiste à examiner l'état ou les performances de l'enduit superficiel d'usure, ce qui permet ainsi de disposer d'une indication de la durabilité de l'enduit. La présente norme est applicable à tous les enduits superficiels d'usure (routes, aérodromes et autres zones de circulation). La liste de contrôle donnée en annexe A (normative) est remplie avant de mettre en oeuvre la méthode d'essai.

Overview

EN 12272-2:2003 - Surface dressing - Test methods - Part 2: Visual assessment of defects is a CEN standard that defines practical, repeatable visual methods to assess defects in surface dressings used on roads, airfields and other trafficked areas. The standard provides both a rapid qualitative checklist (Annex A, normative) and a more detailed quantitative procedure (Annex B, normative) to evaluate condition, performance and likely durability of a dressing.

Key topics and requirements

• Scope and test sections: Visual assessment is carried out on a 100 m ± 1 m lane section. Lane width is defined relative to markings and kerbs.
• Defect types covered: fatting up, tracking, bleeding, scabbing, tearing, fretting and streaking - each defined with typical causes and consequences (for example, fatting up and bleeding reduce macrotexture and skid resistance).
• Qualitative assessment (Annex A):
  • Rapid, operator-based inspection using a checklist.
  • Records P1–P4 indicators: P1 = area percentage for fatting/tracking/bleeding; P2 = area percentage for scabbing/tearing; P3 = estimated % fretting; P4 = total streak length (m).
  • Qualitative testing can be used as a primary screen; if defects are obvious, the more time-consuming quantitative method may be avoided.
• Quantitative assessment (Annex B):
  • Measure section width at six positions (~20 m intervals) to obtain mean width W and section area S.
  • Only defects larger than 0.5 m² are counted.
  • Area measurement rules: rectangular defects = length × width; non-rectangular defects = length × 0.8 × maximum width.
  • Special rules apply for repetitive defects and for expressing results as percentages or lengths (full details in the standard).
• Reporting: Test report formats are standardized so qualitative and quantitative records are compatible.

Practical applications and users

This standard is intended for:

• Highway and airfield authorities and pavement maintenance teams
• Contractors performing surface dressing installation and quality control
• Pavement engineers and forensic investigators assessing dressing failures
• Consultants specifying acceptance criteria and long-term monitoring

Common uses:

• Acceptance testing after surface dressing application
• Routine condition surveys and performance monitoring
• Supporting decisions on remedial works or design changes (e.g., binder selection, chipping size)
• Complementing laboratory adhesion tests and other EN 12272 series methods

Related standards

• EN 12272-1: Rate of spread and accuracy of spread of binder and chippings
• EN 12272-3: Determination of binder-aggregate adhesivity (Vialit plate shock test)

EN 12272-2:2003 is a practical, field-focused standard for consistent, comparable visual evaluation of surface dressing defects - essential for asset management, safety (skid resistance) and lifecycle planning.
